The extension must be.kml. In the Limits section you can enter a value controlling the appearance of the data shown in Google Earth (GE). RL values less than the value in the low limit box will be shown with the low color. RL values higher will be shown with the high color. This feature is not available presently for Qd. In the Labels section you can decide the appearance of the text shown on the measurements shown on the screen. In the example below ID(seq) are shown Tick Auto start Google Earth and Google Earth will start automatic when OK is pressed and the position of the measurements (from the.kml file) will be shown. 10 LTL-XL RSC DELTA

The text shown with the data point in GE is the Series ID and sequence number for the RL measurements. If you click on a data point in GE a box will pop up showing the further information about the measurement e.g. the RL value. Note: Google Earth must be installed on your PC to view the kml data file. Using "Google Software" you agree to be bound by the following terms of service as well as the terms found on our Legal Notices page at http://www.google.com/intl/en_us/hel p/legalnotices_maps.html or existing Google Terms of Service.

GPS signal The quality of the GPS signal is indicated by two sets of data satsinfix gpsdhop satsinfix shows the number of satellites present for location establishment during measurement. The more satellites present the better quality. gpsdhop shows the uncertainty of the GPS signal. A DHOP value <1 shows a high quality. DHOP signals between 1 and 5 shows an acceptable signal and DHOP values >5 a week signal. 12 LTL-XL RSC DELTA
